LU BRICATO R.

SPECIFICATION forming part of Letters Patent No. 563,224, dated J' une 30, 189.6.

Application led February 20, 1896. Serial No. 580,091. (No model.)

T0 all whom it may concern:

Be it known that I, WILLIAM JOHN FEE- GU SON, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Automatic Oilers, of which the following is a specification.

This invention relates to an automatic oler for machinery and engines.

The invention consists of certain new features of construction and new combinations of parts, which are hereinafter described and claimed.

In the accompanying drawings, Figure lis a side view of the oiler. Fig. 2 is a vertical section of the oiler. Fig. 3 shows three views of the adjustable cone-plug. Fig. 4 is a side elevation and bottom view of the central tube. Fig. 5 is a horizontal cross-section on the line 5 5 of Fig. 1.

The letter A designates the oil case or receptacle, which may be of any desired shape. This case preferably has a mica side b, and at the top has a neck c, which is closed bya screw-cap d. This cap has an air-vent e, which opens to the atmosphere at the side of the cap.

In the center of the oil-case is a vertical tube F, which has holes or perforations g in its side; a bottom h, cone-shaped on its lower side, with a round discharge-orifice i in the center, and a neck or tubular extension j below said bottom, screw-threaded eXteriorly, as at j. The upper end of this tube is closed by a screw-cap la. The bottom h, containing the discharge-orifice t', while here shown in the tube F, is coincident with and may be made part of the bottom of the oil-receptacle.

The oil-case A has at its lower side, diametrically opposite the neck c, a shank L. This shank has a lateral opening m through it, and on it has a screw-nozzle n, which latter has an oil-passage o extending through it. The formation of the said lateral opening provides two side bars p. A throttling screwplug with a tapered point is employed to enter the discharge-orice t' in the bottom of the tube F, and said plug is vertically adjustable and is adapted to increase or diminish the size of the oil-discharge opening. The said Screw-plug Q has a concaved or dished top r to correspond with the cone-shaped bottom of the tube. At the center of this dished top is a tapered plug-point i', and a passage s is below the point and extends down through the plug. Two branch passages s' open at said dished top--one branch on each side of the point-and the two branches join the said passage s. This screw-plug is interposed between the bottom of the oil-receptacle and 6o the screw-nozzle n. On the exterior the plug has a screw-thread ja, which screws into the interior tubular extension 7'. This enables the screw-plug to be vertically adjusted. This plug also has a ange t, provided on the exterior with circumferential pits u. It Will be seen that by turning the plug Q its tapered point 1l' may be entered more or less into the discharge-orifice i (see Fig. 2) and thereby diminish or increase the capacity of 7o said orifice, so that lthe amount of oil it will discharge may be regulated to a nicety. The said orifice may be entirely closed,very nearly closed, or may be left wide open.

One ofthe side bars p of the shank has a lateral hole o, and a pin 'u' plays in this hole. This pin is attached to the free end of a leafspring o2, xed on the side of the shank. The spring normally presses the pin fv, so as to keep its end in engagement with one of the 8o pits or indentations on the plug Q, and thereby the said plug is prevented from turning after it has been set. By pressing the spring outward the end of the pin will disengage from the pit and then the plug Q may be turned.

A short glass tube w connects from the iiange t of the plug to the oil-passage o, or around said oilpassage. This glass tube passes down the lateral opening m in the 9o shank. The feed-oil which drops from the orifice t' can be observed by inspecting the glass tube. The glass tube may be dispensed with, if desired.

The perforated tube F is intended to be packed with absorbent material, such as cotton or wool, or sponge.

From the foregoing description the operation of the device will be understood.

Having thus described my invention, I rco claim- 1. In an oiler, the combination of an oilhrei ceptacle having a discharge-orifice; a screwnozzle having an oil-passage in line with said orifice; two Side bars integrally connecting the oil-receptacle and said nozzle and holding said two parts relatively immovable-said two bars forming an open space between said oil-receptacle and nozzle; and a plug located in said open space and having a screw by which it is vertically adjustable and an upward-projecting tapered point which enters said discharge-oriiice and provided with an oil-passage which conducts the oil from said orifice.

2. In an oiler, the combination of an oil-receptacle having a discharge-orifice; a screwnozzle having an oil-passage in line with said orifice;v two side bars integrally connecting In testimony whereof I afx my signature in the presence of two witnesses.
